Re: [Qgis-user] QGIS to manage cadastre
Hi I am french and work with the cadastre and Qgis .. The plugin is really a good plugin but you must know the data are in two categories : all the data with geometry are accessibles by all but you don't access to the data of owners and all others taxes informations ... Only locals gvt can access ( or the studies organisations working for ..) to these informations .. And such studies need a good practice of the relations and request 1-n ...

Re: [Qgis-user] spatialjoin
Hi at all i succeed !! thank's at all ...Andrew was right ... but i add an another thing ; i have indicated in the dialogue box , under "default value" , in "relational value" the name of the layer B , the right field etc... and now it's ok ! one more time , thank's !! laurent Le 21/12/2016 à 23:32, Andrew a écrit : Regarding the default values option/limitations, I can add that if you try to use the default values expression dialog to build an expression using geomintersects() the dialog will evaluate the expression as invalid. Instead, build the expression in the field calculator and then copy/paste it into default value box and skip using the expression dialog.

In fact , i don't use a GPS because these points don't need precision : they are only used to identify the parcels .

With booth data ( number of parcel and name of owner ) , i could talk with the fisc administration :-) Randy was right ...i didn't have the same EPSG for the two layers . It's now OK ! but without the feature "dynamic" . Indeed , i would avoid building many temporaries layers and i thought it existed a plugin for this " dynamic" feature.

Thank you anyway ! laurent Le 21/12/2016 à 17:46, Bernd Vogelgesang a écrit : Hi, for me this sounds more like he is getting new points once in a while and wants to join those attributes to the new points "automatically" from the parcel layer. The biggest problem for users is to rethink the workflow from the end to the beginning and to know the limitations. The outcome should be a point layer with the polygons attributes. If those points (layer A) are from GPS as Randy assumes, they have to be reprojected to the parcels layer (layer B) before being able to join them spatially(layer C). The spatial join in the toolbox produces layer D. Most probably, the resulting layer D is going to to be edited in some way (adding notes about size, the progress, classifications, whatever), so you will have to find a way to preserve those new attribute while being able to add new points without much trouble. The processing toolbox is a good way to do these steps, though it produces a lot of temporary files cluttering the project. A better way for all those repetitive tasks, is to use the graphical modeller, to create a workflow which only has to be triggered once new points come in, and the resulting file can be saved as new a file e.g. with the current date in the name, so you have kind of an archive and do not

And i need a dynamic join because I have no desire to make the spatial join each time...
